position.i4.v = fndfst(string.i1a.r, length.i4.v)

	This routine will return the position of the first non-blank
	character from the left in "string" if "length" is greater than zero
	or the first from the right if "length" is less than zero.  A value
	of FALSE is returned if there are no nonblank characters.
	(Note: This is an archaic entry point.  It has been replaced by

	string		string to search
	length		length of string to search

	This function returns status values as follows:

	FALSE			non-blank character not found
	otherwise		position of non-blank character (starting at 1)

	This function requires the following include files:

	cnsparam_h, cbslib_h
